Application filed April 9, 1913. Serial No. 759,876.

To all whom it may concern Be it known that we, HERBERT W. Mourns and EDWARD M. Mourns, citizens of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in GlassCutting Machines, of which the following is a specification.

This invention relates to improvements in machines for cutting ornamental or other designs upon glassware or the like.

In its preferred form it embodies means for automatically cutting a pattern of any degree of complexity upon the surfaces of articles of glassware.

In the accompanying drawings, which illustrate one preferred embodiment of the invehtion: Figure 1 is a side elevation of a machine, three stones being shown mounted in place therein, but it being understood that as many stones may be used as is found necessary to produce the desired pattern. Fig. 2 is a section on line II-II of Fig. 1. Fig. 3 is an elevation of the rear end of the apparatus. Fig. 4 is an elevation of a tumbler showing one type of design which may be .cut by the machine although it is to be understood that the machine may be used to produce any style of cutting on articles of various shapes. Fig. 5 is a section on line VV of Fig. 1. Fig. 6 is a side elevation, on an enlarged scale, showing one of the tracks with tumbler carriages thereon and showing three stones and their supporting means, parts being shown in section. Fig. 7 is a plan View of a portion of the track with carriages thereon, one of the carriages and the tumblers carried thereby being shown in horizontal section. Fig. 8 is a detail side elevation showing a crown stone with a tumbler carriage passing thereover, the tumbler carriage and tumblers being shown in section. Fig. 9 is a detail perspective view of acrown stone and guard there for, a portion of a tumbler being illustrated in contact with the stone. Fig. 10 is a fragmentary vertical section, on an enlarged scale, through the crown stone and its guard and showing a portion of the tumbler. Figs. 11 and 12 are diagrammatic views showing disk stones of different sizes and the guards therefor. Fig. 13 is a side elevation, partly in section, of a modified construction of track, tumbler carriage and support fonone, of the stones. Fig. 14 is a section oniine XIV--XIV of Fig. 13, the stone, driving pulley and guard being shown in elevation. Fig. 15 is a section through a portion of the track and carriage taken on line XV-XV of Fig. 13. Fig. 16 is an edge view of an improved form of cutting wheel. Fig. 17 is an edge View of av wheel of similar construction, but having a grinding surface of different shape. Figs. 18 and 19 are views illustrating cuts made by the wheels shown in Figs. 16 and 17.

The machine illustrated is designed particulariy for cutting patterns on tumblers or other articics of approximatetly cylindrical shape, but it is to be understood that the invention. is not limited to such use but may be employed for the cutting of other ar-' ticles of various shapes and made of any material adapted to be cut.

In the construction shown 1 is a suitable framework carrying brackets 2 and 3 which support the shafts I of large pulleys 5. The shaft for the pulleys at one end of the machine, for example the front end, are preferably journaled in boxes 6 sliding in slots 7 in the bracket 2, screws 8 being pnovided to adjust the boxes longitudinally in the slots. Parallel tracks 9 and 10 extend between the pulleys. Traveling along these tracks and over the pulleys at the ends of the apparatus are the carriages 11 for the tumblers or other articles to be cut. Each carriage, in the form of the invention illustratcd,.is adapted to carry two tumblers and comprises a pair of end members 12 connected by a shaft or cross bar 13 and carrying the tumbler holding mechanism. The carriages 11 are preferably connected to form on endless chain, as by means of the links 14, and they may be propelled by any suitable mechanism, for example, by direct engagement with the pulleys 5. Driving cables 15- are preferably provided, however, which pass over the pulleys and are connected to the chain of carriages at one or more points in any suitable manner, as, for instance, by the clips 16. As will be understood, the carriages may each be connected directly to the cables in which case other connections between the carriages, such as the iinks 14,

could be dispensed with. In addition to propelling the carriages the cables serve as supports for the same while they are passing back over the upper'track 9, as shown in .Fig. 2-, The cables are propelled by the rothe shaft 4. or otherwise driving the cables and carriages may be adopted.

The means tor holding the articles to be cutmay be of any suitable type and obviously will vary with the nature of the articles. The construction shown which is well adapted tor holding tumblers or similar as ticles comprises a chuck 3O journalcd on a short shaft 31 mounted in one of the end members 12 of the carriage. The chuck 30 has a cup-shaped recess 32 to receive the bottom of the tumbler. The open end of the tumbler is engaged by a plug 33 which is slidably mounted upon a short shaft 34 carried by the end member 12 at the oppo- Site end of the carriage, the plug being forced into the.end of the tumbler by a sprin 35. Means are provided fonrotating the tumbler on its own axis so as ;to present the proper portion of its surface to the action of the cutting wheel, as will be hereinafter explained. This rotation is preferably, but not necessarily, continuous during the cutting operation as well as during the intervals between the making of successive cuts. In the form of the invention illustrated, this axial rotation is imparted to the tumblers by means of gears and 37, the former being attached. to the chuck 30 by means of a sleeve 38, while the latter is connected to drive the plug by means of rods 39. The gears 36 and mesh with the teeth of racks 40 which form pa rt of the lower track 10. As the chain of carriages is drawn along it will be seen that the cngagenient of the gears with the rack will cause a. uniform rotation ot' all of the tumblers carried by'carriages passing: along the lower track. The tumblers are inserted in their holders by drawing back the plugs 3 inserting the bottoms of the tumblers in the recesses it): andpermitting the plugs to he forced into the open ends of the tumblers by the springs One of the guide rods 39 may be provided with a s on to prevent the plug from mining of? 2837 the tumbler is removed.

The cutting of the pattern upon the tuniblers is done by means of winding wheels or. stones mounted between tr: l0 and preferably 3I3j)l-Tl cvoli it ll. be understood tliat nallm'us of the h nd usually cut upon gla var-c 'n of a it??? number of separate 30 duce the d'esired'au made present invention a series of stones or abradin; wheels is used, each stone being intended to make a single cut in the surface of the glass, the stones being; so placed that when the glass has passed over all of them the cuts will be locat d on its surface in the de sired pattern. .\ny number of stones may be used so that a pattern having any num ber of individual cuts may be produced and the stones may be of different characters so as to produce cuts of various kinds. example ol' patlcrn capable of being cut by the ma hine of the present invention is Fig. 1. This pattern comprises his 0;" cuts-petals J0, leaves 51 and seems 3.32. The petals are cut by disk stones ha ring rounded edges and known as punnie stones. Such a stone is illustrated at 53 in Fig. 6. The leaves are cut by disk stones having beveled edges and known as leaf stones. such a stone being shown at 54 in Fig. 5. The stems 52 are cut by crown wheels or stones 55, such as the stone illustrated in Figs. 8. 9 and 10. The disk pimn e and leaf stones. such as and 54:, are well known in the art, but the crown stone shown in Figs. 8, 9 and 10 is believed to be a new and valuable feature ofthe present invention. It will be understood that the stones referred to are merelydllustraticns of those which may be used, as any desired type of stone or abrading device may be employed as required by the pattern which it is desired to cut. The stones are .mounted in such manner that they may be adjusted as to elevation and transversely between the tracks so as to place the cuts upon the desired portions of the tumbler surface. The planes of rotation of the disk stones are also capable of being adjusted so as to place the cut at the desired angle upon the surface. As shown. the disk stones are mounted as follows: The shaft of the stone iourimlcd in boxes (30 which are capable of vertical adjustment bctween guides 61 formed on the arms 62 of a yoke. The latteris mounted on a column Gil, preferably of square or other non-circular section, which slides in a sleeve 64. the outside of which preferably cylindrical. Means are prutcrably provided for adjusting the column (33 vei-ticiilly in the sleeve til, these means comprising, in the form of the-invention illustrated, a screw 65 journaled in the lower curl oi the sleeve and screwing into an internally "'cudcd socket in the column.

A hand wheel 66 provided for, rotating 71. l t-will be seen that the cross bars 67 may be adjusted on the stringers either longitudinally or laterally ot the machine, and

., that the sleeves 64 may be adjusted angugage the surface of the glass.

larly and held in position by the clips 68. The column 63 is held against rotation in the sleeve tJ-i, owing to its non-circular section, and thus the plane of rotation of the stone may be determined by adjusting the sleeve 64.

Any suitul le mechanisln for rotating the stones may be utilized. As shown. a pulley 72 is mounted upon the shaft of each stone, While running longitudinally of. the frame of the machine is the driven shatt 23 which is connected to the motor 24 as above described. The shaft has fixed to it a number of pulleys 73 from which power is transmitted to the pulleys 72 by bolts 74. Means are preferably provided for keeping the stones wet, the means shown comprising sponges held against the stones by clips 76., The sponges are supplied with water through flexible pip s 77 connected to a longitudinal feeder B. It is obvious that other arrangements for moistening the stones might be used or that stones might be re placed by Wheels of suitable material fed with an abrading substance in the form of dust or paste.

The vertical adjustment of the stones permits the adjustment of the machine for operation upon articles of different diameters. audit the articles to be operated on are allot exactly uniform dimensions the depth of the cut could also be determined in this manner. it a feet, however, that glass blanks are always found to vary considerably in thickness and other dimensions so that it the tumblers or other articles are moved in a fixed path across a series of fixed stones uniform cuts will not be produced. l! the glass is thicker than normal,

the cut will be deeper, while if. it is thinner the out will be shallow or will not be made at all. The presen invention provides means for emnpensating for the inequalities of the glass and insuring a cut of the exact depth required in every case. These means comprise the mounting of the glass and the stones in such manner as to permit a. relative yielding movement thereof, each stone be ing provided with a guard which determines the depth of the cut. In the form of the invention illustrated this guard comprises a plate 80 mounted on the upper ends of the guide bars (31 and having a slot 81 therein through which the upper portion of the stone projects. At each side 01' the slot are the guide ribs 82 which are designed to en The edges of these ribs are prelcrzzl'ily curved to an arc of greater radius than that of the stone. The stone may lH adjusted to project more or less beyond thesi. edges by means of the screws 83 which engage the'boxes fill and adjust the boxes between the guide bars 61.

In the form of the invention illustrated in Figs. 1 to 7, the stones and guards are, when once adjusted, mounted in rigid position, the tumblers being held in contact therewith by gravity, so that as they move across the guards they may be lifted by the curved edges of the guide ribs. As the tumblers may yield away from the stones in this manner it will be seen that the depth of the cut is determined definitely by the amount which the edge of the stone projects beyond the guide ribs. The weight of the tumblers and carriages is suiiicient to hold the tumblers in contact with the guide ribs and stones so that the maximum cut permitted by the guide ribs is always made. he linking of the carriages together intoa chain facilitates the holding down of the tumblers. as each carriage is held down not only by its own weight but to some extent by the weight of the carriages on each side of it. The guide ribs not only determine the depth of the cut made in. the tumbler but also determine its length. It will be seen that the tumbler is rotating slowly all the time as it passes over a stone so that the longer the period in which it is in contact with the stone the longer Willbcthe cut made in it. The length of time during which the glass is in contact with the stone depends upon the length of the exposed portion of the periphery of the latter which. is determined by the relative curvature of the stone and the edges of the guide ribs. This action of the guide ribs clearly appears from Figs. 11 and 12. Fig. ll shows a gun: rd applied to a stone of comparatively small diameter, the full lines showing the stone in position to make a short shallow cut. By raising the stone relatively to the guard to the dotted line position it will be seen that a deeper cut will be made. Fig. 12 shows'the same guard applied to a stone. of larger diameter. It will be seen that the full lines show the stone making a cut of up proximately the same depth as the cut made in the small stone shown in Fig. 11 in full lines but of considerably greater length. This is due to the larger diameter of the st one. The raising of the stone to the dotted line position makes the cut deeper without materially affecting its length. The elevation of the stone is preferably so adjusted that it will make the desired cut in a. glass of the minimum thickness without lifting the glass substantially. lVhcn a thicker glass is brought into contact with the stone it will be raised slightly by its contact with the guide ribs so that the identical cut will be made in it as is made in the thin glass. The variations in the thickness of the glass are, bowmer, not great so that in no case is thrglass lifted sufficiently to disengage the gears 53 and 37 from the racks or to interiere with the satisfactor operation of such gears. It is obvious that instead of mounting the glasses in such manner as to permit them to yield, the stones may be mounted to yield as shown, for example, in Fi 13. l

or making curved cuts upon the tumblers or other articles to be cut. one or more crown stones may be employed, as the design may demand. These stones rotate about axes prefierably substantially perpendicular to the plane of movement of the surfaces to be cut and have annular cutting edges which rotate substantially in that plane so that the glass surface may be brought into contact with a considerable are of the cutting edge at the same time. This results in the production of a curved out which may be made of any desired length. These crown stones may be mounted in any suitable manner. As shown, each is mounted on the upper end of a shaft 90 which is journaled in a frame 91 mounted on a column 92. The column may be slidab y mounted in a sleeve. as shown in Fig. 1, or it may besupported in the same vay as the sleeves 64 above described, that is, by being secured directly to'the cross bars 67 by cli is 68, as shown in Fig. 8, although obviously any other supporting means for the column may be utilized. Any suitable form of gouring may be employed for driving the crown stone. As shown, the shaft has a beveled gear )3 fixed to it which meshes with. a bcvcled gear 94 which is driven by means of a pulley 95 and belt 96 from one of the pulleys 73 on the shaft 23. A guard 97 is preferably cmplc ed for determining the depth of the cut to be made by the crown stone in a manner similar to the action of the guards used on the disk stones. In its preferred form the guard is provided with a vertically adjustable guide flange J8 which extends approximately half way around the stone, the guard being mounted in such manner that it may be located in any desired position of angular adjustment around the stone. As shown. the guard is supported by a yoke 9.) which is secured to the column 92 by a clamp 100. The guide flange 9% is secured to the guard in any suitable manner, asby means of screws 101 passing through vertical slots 102 in the flange. Three screws are preferably employed. one located at each end of the. flange and one near the middle so that "either end of the flange may be caused to'nrojcct beyond the cutting edge of the stone or the ends may be depressed and the central portion of the flange raised up above the cutting edge. 'By the adjustment of the guard circumfercntially ot the stone and the vertical fldlllSilillQllt nf tilt guide flange, a curved out may be made of tiny length up to a com nlete circle. By raisudjusted position by a set screw 1'12. obvious that instead of this construction. the

ing the central portion of the guide fla s-.2 and dropping the ends thereof, an interrupt ed cut may be made. Such acut is shown ir the design illustrated in Fi 4, in which the stem out is interrupted in the middle where the flower is placed. The crown stone may have cutting: edge of any desired are provided with longitudinal" grooves 111 which receive the IKhfiitld ends 112 oi the tumbler holilastuds and so prevent the lifting of the tumbler carriages as in the form of the invention ab ve descri ed. In order to provide the necessary relative yielding between the Strui'ns and the tumbler carriages to allow for in qualities in the thickness of the glass and for the maki 1g of cuts of various lengths in the "ll ll('! ol' the glass. the stones are yiclila ly mounted. As shown. car-h stone H3 is imirnaled in a voln lll m unted on a column 115 oi non-c rcular ClUHSfivtFl'lflll wh ch adapted to slide vertically in a Nlt'lYl vliii'li may be at tached to the (i :=s l::i2-- n illlll. stringers it as aboie d wriirr-il. or otherwise suitably supported. i column Ill? has a collar ll? fixed flu-won whit-ll is eugby a coilci'l spring ill. the i u'or end I the HIJPQR wi l (11 lilo slevn li To limit the upwaid moi pent ol the column a suitable stop is provided. uch a the not lift screwing on the stud which projects from the lower end i "the column. This stop. it nill be 11cm]. (l os not prevent the downward movement ,of the column but limits the upward movement thereof and it may be adjusted so as to determine the initial elevati n oi the cutting edge of the ;-1l' l1o. The stone is provided with a guard 12!. similar to the guard Si above described and for the same purpose. in this form of the apparatus, however, the guard instead of raising the tumbler. is itself depressed by contact with the latter. thus depressing the yoke ill. and the stone carried thereby. As shown. the guard mounted to slide vertically in a slot in the yoke, it being hell; in t is construction shown in Figs. 1 to 7 could be cmplo md, in which the guide is fined to the yoke and the stone'is journaled in adjustable lwaringzs, andv also that the construction shown in Figs. 13 and 14 could be substiiutcd for the construction shown in Figs. 1

to 7, if desired. Fig. 13 also shows a construction which may be utilized to adjust the plane of rotation of the stone. As illustrated, the yoke 11 1 is pivoted upon the upper end of the column 115 and is provided with a Worm gear 123 which is engaged by a Worm i524 journaled in a bracket 125 attached to the column. A. hand Wheel 1526 is provided for rotating the Worm. By rotating this hand Wheel it will be seen that the yoke may be swung upon the upper end of the column and thus the sione be set to rotate in any desired plane.

' Figs. 16 and 1''! illustrate two forms of a cutting Wheel of novel co rnrlion which may be used in the machine if i; is needed to produce a particular elicct in the pattern to be cut or which may be uaed advantageously in hand cutting. This novel construc tion comprises a series of cutting disks 130 of copper or other suitable material adapted to cut or mark the glass separated by layers 131 of inactive material, such as paper or any other substance which will not mark the surface of the glass. By bringing the glass in contact with a wheel of this construction a number of line parallel lines will be drawn or cut thereon by the edges of the copper disks. In a Wheel of this construction builtup of alternate layers of active and inactive material, the layers oi acti e material may be made as thin desired and may be brought very close together so that it is possible to out very fine lines and place them as close together is desire: this? construction may be utilized to produce various clients, for example, to make a leaf or petal or other figure coinposcd of a number of parallel lines, as shown. at 132 in Fig. 18, or it may be used in connection with a punnie stone to make a figure such as indi cated at 133 in Fig. In making a petal such as indicated at 1 2, lhe glass preferably first hollowed out in tin "laps of tho petal by the use of a punnic stone, after which a wheel of the shape shown in Fig. 16, the periphery of which just fits the doprcssion made by the punnie stone is utilized to draw or cut the lines in the bottom of the depression. A Wheel of the shape shown in 17 is adapted to out or mark a fiat or convex surface of the glass. Such a Wheel may be advantageously rmployed.

for producing; a checkered pattern such as is indicated at 134 in Fig. 19, by first applying the glass to a Wheel rotating in one plane and then to a Wheel rotating in a plane at right angles thereto. Wheels of this novel construction are very Well adapted to use in a machine of the typo herein described but they are also useful for hand cutting as they avoid the laborious and expensive operation of producing figures made. up of fine parallel. lines or checker work by cut- A Wheel of' ting each line separately as has heretofore been the custom.

From the foregoing description it will be seen that an automatic machine is provided. by which a pattern of any design may be cut or marked on a tumbler or other article. In the operation of the particular machine illustrated, the endless chain of carriages may be continuously driven, the tumblers being inserted in the holders as the carriages pass along the upper track or over the pulleys. The tumblers are then drawn along the lower track in their carriages, being slowly rotated through the cngageinent of the gears on the tumbler holders with. the longitudinal racks. The tumblers are thus passed slowly over the succcssive stones which are so set that each stone produces one of the component cuts of the pattern in its proper location upon the surface of the glass. The stones may be of a variety of types so as to produce the different kinds of cuts required to complete the pattern and any number of stones needed may be used. For example, some patterns require the glass to be passed over fifty or more successive stones. It is to be understood, however, that the invention is not. limited to the particular construction of machine set forth. In some cases, for instance Where a pattern involves the duplication of a design upon the surface of an article, the article may be passed more than once over the same set of stones, different portions of the surface of the article being presented to the stones so as to duplicate the pattern,

It will be'obvious that various modifica ions in the structure illustrated may be employed, as, for instance, a difi'erent type of carrier may be utilized for holding the tumblers and presenting them to successive stones or the tumblers may be mounted to rotate about fixed axcs and thcseries of stones may be so mounted as to be successivelv presented in proper relation to the articles to be cut. The articles may be rotated continuously or intermittently, or otherwise suitably moved to present proper portions of their surfaces to the action of the stones. In the case of articles having cylindrical or other curved surfaces, it is usu: lly found desirable to rotate the articles about their own axes While in contact with the stories but this rotation is not essential and in the case of articles ha ing flat surfaces would ordinarily be objectionable In the claims the cutting elements will be. designated. for convenience, as stones but it is to be understood that any type of abrading means, Whether an actual stone or a metal Wheel fed with powdered abrading material, or other construction, is intended to be covered by this term..
